Please answer the following question:

How does the group know which are its members?
Or how does Kingsley's server know which are the members of the group?

You will find that unless the server knows about the foaf profile to check, it would have to do a complete crawl of the whole web to find out.

No, everybody controls some piece. Having everybody control everything is a recipe for confusion. 

So Kingsley's server controls the group that gets access to the the ACLed picture.
Kingsley is kind enough to put just one condition on being a member of that group, to reduce spam: 
 1. you must add your membership to that group to your foaf
 2. you ping the group when you have done it.

The elephant in the room?
